Swinject is a lightweight dependency injection framework for Swift, implementing inversion of control via a DI container. It helps split apps into loosely-coupled components that are easier to develop, test, and maintain.

Use cases

• resolve dependencies in a Swift iOS app with a DI container
• inject dependencies into view controllers via initializer or property injection
• manage singleton and transient object scopes in Swift
• break circular dependencies between Swift services
• make Swift code more testable with mock dependency injection
• organize app modules with assembler and container hierarchy

When to choose

• you're building an iOS/macOS/tvOS/watchOS or server-side Swift app and want loosely-coupled, testable components
• you need a mature, actively maintained Swift DI framework with object scopes and circular dependency support

When to avoid

• your project is small enough that manual initializer injection is sufficient
• you're not using Swift or the Apple/Linux Swift ecosystem
